Learning The “Secrets” of Questions

Due to the sheer size of space, it contains trillions of objects and galaxies that are out of this world, here are some incredible facts about space.

The first awesome fact about space is that it is completely silent. Unlike Earth which has atmosphere, Mars does not have air or gases that permit sound to travel. Also, in order for sound to travel, there needs to be molecules to vibrate, but in space, there is large empty spaces between the starts and planet hence there will be no molecules to vibrate.

Another fact is that the space has more stars than the sand on beaches on Earth. The universe is estimated to have 10 trillion galaxies and when that number is multiplied by the milk ways estimated 400 billion stars, then you a very large number of stars that is uncountable.

Apart from planet Earth, Mars is another planet in the solar system that is believed to have life. On Mars, there are some areas that have the presence of liquid water which shows that life exist in such places. Besides, there was a research done in 1986 by NASA where they recovered fossils of living things in a rock.

The universe has very tiny stars with only a radius of 10 km known as the Neutron stars and they are known to spin 600-712 times per second. They can rotate up to 60 times per second when they are born from a star explosion. They have a mass greater than that of the sun and due their physic, they can spin very fast in just a few seconds.

Space has thousands of other planets outside of the solar system. These extrasolar planets are in orbit and can be found around another star. To date, almost 1800 planets have been confirmed as research goes on to identify which of these worlds is habitable.

Although the sun is considered an average size star, one million Earth’s would fit in it. The sun’s mass accounts for 99.86% of the entire solar system. Therefore, due to its sheer size, it means that millions of earth can be able to fit inside it.

Venus is the only planet that has a day longer than a year. This indicates that it takes 244.7 Earth days for Mars to complete a whole orbit around the sun. However, it takes less time for Mars to rotate its own axis which is 423 Earth days.

Astronauts do not walk in space otherwise the skin of their feet will peel off. This is because they wear the socks for a few days and the skin of the feet becomes soft and flakens off.
